BLIND SUMMIT PUPPETS
INTRODUCTION
The Blind Summit Puppets site gives information on how I make the
puppets we use in our shows. It explains the processes and techniques
and includes information about the materials. I have tried not to be
too technical and not overly detailed it is impossible to explaineverything and if you are interested in making then the best way to
learn is to get stuck in. !owever" I guess if you#re reading this"
then you have an interest in knowing more" and will probably put up
with a bit of technical chat and the occasional use of words such as
thixotropic and exothermic.

The puppets that we use are inspired by )apanese Bunraku Puppets.
*lthough the materials and construction methods vary greatly" and the
look of the puppets is not usually )apanese. !owever" our larger
puppets are often over a metre in height" similar to the height of
Bunraku puppets and they are fully operated with three people$ one on
the head and the left hand" one on the right hand" and one on the
feet.
The si+e of the puppet is largely driven by character and the context
in which the puppet will be used. ,e have puppets ranging from about
-cms to /. metres in height. The larger the puppet gets" the more
difficult it is to operate. I think the puppets are more interesting
when they are smaller than human si+e and in some cases considerably
smaller.
%epending on how impatient I am to begin" I may do a full si+e plan of
the puppet. This is more important if I am making several puppets for
one show which have to relate in scale to one another. I often dotechnical drawings for some parts of the puppets" particularly the
arms and legs" in order to work out the shape of the limbs and the
positions of the pivot points for 'oints.
I tend to make the puppets head smaller proportionally to the rest of
the body than it would be in real life. This is personal preference"
for me it makes the puppet look more elegant and real.
The expression which I sculpt for the puppet head will again be
dictated by its character. I tend to sculpt expressions that are not
too extreme" it seems to allow a wider range of emotion when we are
using the puppet. I usually sculpt the mouth slightly open. *gain thisis personal preference and not always the case" but I think it gives
more possibility that the puppet is talking or perhaps 'ust active.

Head
How te uets are ma"e###
The first part of the puppet to be sculpted is the head" which I tend
to sculpt from some sort of visual reference. 0ither a photo of
someone in particular" or a drawing. 0ven when working from a photo" I

find it useful to do a drawing" as it helps me to understand the
features and structure of the face.
I sculpt the head in either plastaline or clay.
1rom this original" I make a mould" using silicone rubber encased in a
fibre glass or 'esmonite shell. The shell provides the silicone with
support when the original is removed. I clean up the mould and then
make a resin and fibreglass cast.
Sculti$%
*n armature is needed to support the sculpted head. 1or plastaline I
use a wooden ball fixed to of a piece of dowel" supported in a woodenbase. 2&lick the image to see an animation of a head sculpt3. The
advantage of plastaline is that it doesn#t dry out and shrink" this
means that it is easier to work on something over a longer period.
!owever it can be a bit more difficult to get a uniformly smooth
finish.
If clay is being used then the armature cannot be solid" it needs to
be something with give. This is because the clay shrinks as it dries
out and so compresses whatever is inside it. To prevent the clay
cracking around the armature you need a soft core at the centre. I use
wet sheets of newspaper folded into one long strip" wrapped as tightly
as possible around the end of a piece of dowel" and secured with wire.
4ou can then add small bits of clay and build up the head. ,hilst
working with clay you must keep it as moist as possible" spray it with
water frequently and wrap it in plastic when you are not working on
it.
,hatever material you sculpt in" the armature needs to be strong

enough to support the si+e of head you plan to sculpt. * relatively
small head" /5cms from top of head to bottom of chin" can end up using
almost - lbs of plastaline.
1or the eyes I use beads. It can be difficult to know exactly where to
position them" especially early on when there is little of the head to
know where they should be placed. I try to place them as accurately as
possible by taking measurements from the drawings. But often it is
'ust trial and error. I have occasionally got quite far with the
sculpt only to reali+e that I need to move the eyes further forward or
back.
* finished clay sculpt can be sealed either by spaying it with a
plasticised aerosol paint" or by applying a layer of shellac varnish.
Moul"i$%
The type of mould you make is determined by the material in which youare sculpting and the material in which you intend to cast the
finished item. I usually cast the head and hands of the puppet in
resin with fibre glass so the end result is a very rigid positive.
This means the mould needs to flexible if it is going to come away
from the details of the face and pull out from any undercuts without
doing any damage" and remaining reusable. The best material for this
is silicone rubber. It is very flexible and provides a highly detailed
cast" picking up every mark and texture of the sculpted body part.
To make the mould I begin by building a clay wall around the head of
the puppet. By doing this you define the seam line where the mould
will separate and the two parts of the head will 'oin together when
you later cast the finished head. I take the seam line over the top of
the head along the edge of the ear and down 'ust along the bottom line

of the 'aw.
4ou can build registration marks into the mould by making small
hollows or protrusions in the wall. This means the two halves of the
mould will line up accurately should you want to 'oin the head cast
whilst it is in the mould. 2Because of the need to put fixings inside
the head" I usually end up assembling the head out of the mould. This
can make it harder to match up the edges" as they often distort
fractionally when the cast is removed from the mould" making it
difficult to line up exactly.3
I then make the first silicone part of the mould. This is best done in
two stages. 1irstly a thin layer of silicone brushed gently over all
the features and into the details of the face" and when this has
cured" a thicker layer 67mm thick. This can be done in one go" but it
is more difficult8 in order for the silicone not to slump" you need to
add a thixotropic agent to the thicker layer" which makes it harder to
brush into the more detailed parts of the face" around the eyes andthe nostrils and ears" and increases the likelihood of air bubbles.
The silicone on its own is not rigid enough to cast into" when removed
from the sculpt it will be soft and flexible. So the next stage is to
make a rigid case to support the silicone. 1or this I use resin and
fibreglass" completely encasing the silicone and brushing around the
edge of the clay wall. 2If the clay is not too damp there shouldn#t be
any problem with the resin going hard.3 I build up three or four
layers with a couple more around the edge of the mould for extra
strength.
,hen the resin has fully cured I remove all the clay from around thehead and clean up the back of the mould and head. Then I spray a wax
based release agent onto the exposed edge of silicone and repeat the
process for the second part of the mould. Before encasing the second
half of the silicone mould in resin and fibreglass I put a thin layer
of vasaline around the fibreglass edge where the two halves of the
mould will meet. This will ensure the two halves separate and do not
'ust become one solid shell.
To seperate the mould I trim back the edge of the fibreglass to get
rid of the rough edge" to where it is a bit thicker. Then" using a
thin tool or chisel" I gently work around the mould to prise it apart.
2,hen building up the fibreglass shell for the mould I tend to make
one or two areas around the edge a bit thicker so there are some
stronger points at which to lever open the mould.3
1inally I clean up the mould to prepare it for casting.

,hen the mould is finished the head is ready to be cast.
I use polyester 2plastic3 resin and fibre glass to make the puppet
head. The resin is a liquid and can be brushed or poured into the
mould. It is mixed with a small amount of catalyst which causes it to
harden. I do not usually pour resin" as a solid resin head is far too
heavy to be of any use. *lso" on its own" resin has very little
structural strength. To prevent it shattering" it must be used with
fibreglass. The resin impregnates the fibreglass and the two materials
create a very strong and reasonably lightweight structure.
I build up the head by brushing layers of resin and fibreglass into
the mould.
Te Hea" Meca$ism
9any of the puppets that we use have a tilting head mechanism which
pivots the face upwards around a point where the head meets the neck.This simple mechanism gives a huge degree of life to the puppets
thoughts and movements.
* piece of aluminium tube forms the neck of the puppet" at its top end
a small length of threaded rod pivots around a steel pin. The back end
of this piece of rod is fixed into the inside back of the puppets
head. 2Sometimes it goes through a hole in the head and sticks out the
back" to form a handle for the puppet.3 * wooden handle is drilled to
take the bottom of the aluminium tube. It has an elongated hole cut
into its length through which a small trigger connects to a short rod
within the tube. Through the use of piano:steel wire" the trigger rodpulls down the threaded rod at the top of the tube. It pulls against a
spring connecting the threaded rod to the tube" which returns the head
to its lowered 2resting3 position. ,hen the head is in place on the
puppet" the aluminium tube travels down through a hole into the
puppets body. The shoulder construction of the puppet rests on the top
of the handle 2which has a rounded top to it3" so as well as
controlling the head" the top of the handle is supporting the body of
the puppet.

Hands
;nce the head is sculpted then I begin on the hands. *s with the head"
these are usually sculpted" moulded and cast.
To construct an armature for larger hands I will use a heavy gauge
aluminium wire. The photo is of a larger hand. &lick to change between
the &rmature and the Ha$".
I have wrapped a finer wire around the fingers and thumb" this is to
give the clay something to grip so that it doesn#t 'ust slide off the
wire. The fingers can be bent into position and sculpted individually.
The palm and back of the hand can then be sculpted around them.
1or a larger puppet I will either sculpt the hands in plastaline or
perhaps sculptey. The advantage of sculptey is that it can be heated
and hardened in an oven. 4ou can still make ad'ustments when it is

hard" by carving or sanding and it is a lot easier to create a clay
wall around the hand for moulding than when you use something which
remains soft such as plastaline.
If I am making hands for a very small puppet" then I will probably not
bother with a mould" and instead 'ust make a one off. This will
involve an armature similar to the one above" but much smaller" made
out of steel wire. In place of the wooden support in the photo" I use
a small piece of leather for the wrist 'oint" attached securely to the
wire in the palm of the hand. The armature is attached to a length of
piano wire" pro'ecting from the side of the wrist" which will
ultimately have a small wooden handle for operating. 1or the smaller
hands I will often use milliput to sculpt in" as with the larger
hands" I start with the fingers and thumb" allowing them to harden
individually and then add the palm and back of the hand.
Ha$" Moul"
The moulds for the hands can be quite complicated" depending on the
position they are sculpted in. If the hand is in a relatively open
position" and the fingers are not too bent" then you can create a
simple two part mould. !owever as soon as you start to have the
fingers bent towards the palm" then you may need to consider a three
part mould" in order to be able to brush resin into the mould at a
later stage" and release the cast sections from the mould.
& simle a$" moul"
* mould for the hands follows a similar process to the head mould. I
will usually rest the hand in a bed of clay built halfway up the side
of the hand and in line with the wooden support pro'ecting from the

wrist. ,hen the hand is later cast" the wood will be replaced with
cotton or nylon webbing which acts as a wrist 'oint. The exposed side
of the hand is covered with silicone rubber and when that is cured"
encased in a resin and fibreglass shell. The clay wall is then removed
and silicone is brushed over the other side of the hand. This too is
covered with the resin and fibreglass. It is important to use a
release agent between the two halves of the mould. Before applying
silicone for the second part of the mould" I spray a wax based release
agent on the exposed edges of the existing mould. ,hen the silicone
has cured I apply some vasaline to the rim of the resin shell" before
brushing on resin and fibreglass for the final part of the mould.
Body
Puet torso
0very puppet seems to require a slightly different approach to making
the body. But this is how I usually make the larger puppets.
Sculti$%
1or the larger puppets I start by cutting out the body shapes in 9%1"
using a scroll saw. ,here possible I remove wood from the inside of
the shape to reduce the weight of the puppet. I use these profiles as
templates to sculpt the body parts. I prefer to sculpt the body from a
soft foam rubber as this is the most sympathetic when it comes to

using the puppets. There is no sound when the puppet knocks against
things" it is lightweight and it has some give in it" like skin.
!owever there are often occasions when it is better to use a more
rigid material" like syrofoam. This is usually when the limb will be
seen" and not covered by clothing. 1or example the bottom of legs and
the lower part of the arm. Both materials will need some sort of
covering to protect them. I cover soft foam rubber in stockingette"
which is glued to the surface of the foam with copydex. Styrofoam is
more problematic. I usually cover it with fibreglass and resin" which
can then be sanded to create a smooth finish. !owever" you cannot
apply resin directly to styrofoam" firstly you must apply a barrier
layer of tin foil" which prevents the resin from destroying the
styrofoam.
'oi$ts a$" assem(ly
There can be a lot of pressure put on 'oints and fixings. The arms and
legs have strips of aluminium for extra strength. The aluminium run
the length of the limb" and is bolted to the 9%1 profile. 1or elbow
and knee 'oints" where the movement is like that of a simple hinge" I
drill a small hole in the aluminium and connect the limbs with a

Clay
There are many different types of clay available" and to some degree
it is personal preference as to which one you use. To me it is the
most pleasing medium in which to sculpt the puppet heads" although for
practical reasons I tend to use plasticine more often. I usually use a
simple grey clay from Tiranti#s.
Plastali$e
This is an alternative sculpting material to clay. It#s advantage is
that it doesn#t dry out and isn#t as soft" so you can be a bit rougher
with it. It provides very fine surface detail" however it takes a bit
of practice to get a smooth finish if that is what you want. 4ou can
use lighter fluid and a sponge or brush to smooth it down.
Styro)oam
Some of the puppet parts are sculpted in styrofoam. This is easilycarved to a rough shape with a saw" and can then be with shaped more
carefully with sharp knives. It is finished with various degrees of
sanding.
styrofoam is great to sculpt in. It is very lightweight" and is
available in various densities. It can be sawn" carved" and sanded" to
create quite detailed shapes and features very quickly. ;n the whole
it is better for larger figures" this is for two reasons. 1irstly"

very fine details can be hard to achieve and quite fragile" and
secondly" you will most likely need to cover it with something to
protect the surface and increase its strength. This will inevitably
cause some loss of detail which is far less noticeable on larger"
simpler shapes. The biggest problem with styrofoam is that it#s easily
dented or snapped if you are creating thin shapes 2such as fingers3. I
don#t know of an easy way around this. If I am using it for puppets
then I usually coat it in a harder outer shell before it can be used.
4ou can use 'esmonite" which in some ways is ideal as it has no
reaction with the fibreglass and adheres to it well" but 'esmonite is
quite heavy and I have found it to be less durable than fibre glass.
If you use fibreglass" however" you can#t put it directly onto
styrofoam because it dissolves it. 4ou need to cover the surface
first. Tin foil is a good material for this" and can be glued with P=*
but it is a hassle to have to do. Both fibreglass and 'esmonite will
leave an irregular surface which you will need to sand if you want asmoother finish. *pparently there is a material called peel ply which
can help give a smooth finish with fibreglass. If the puppet does not
have a long life ahead of it and will be treated quite carefully then
it could 'ust be covered with a few layers of tissue paper or muslin"
but the surface will always remain vulnerable.
So)t *oam Ru((er
This is my preferred material for sculpting body parts. It is
relatively light" and can be knocked and dropped with no damage to it
at all. I use an electric kitchen knife to cut and shape it" which is
a long and tedious process" but produces a very good finish. 4ou can
also use scissors" and it can be sanded. 4ou can achieve a good smooth
finish and after I have attached it to the body armature" I cover it
in stockingette" using copydex to give it a more durable and protected
surface. The stockingette also alows the costume to move more freely
over the surface of the limbs with less friction than the foam.
Sculey
SuperSculpey is the brand name for a polymer based modelling clay
which hardens in the oven. I have found it good for hands as you can
harden fingers as you sculpt them.
Milliut

* two part sculpting material mixed in equal quantities of resin and
hardener. ,hen set it is very strong and can be carved" drilled and
sanded. I tend to use it on smaller puppets" to sculpt body parts too
small or fiddly to mould. It is quite heavy and so not ideal for
larger puppets.
,hen using milliput be sure to mix the two parts very well" if there
is any streakiness then they may not harden. 4ou can smooth the
surface with water whilst it has not set.
Silico$e Ru((er
This is the best material for making the head and hand moulds" as it
picks up the detail of the sculpting so well. The only downside is
it#s cost8 unfortunately it is quite expensive.
The rubber comes in two parts which need to be mixed together before
use$ the liquid rubber and catalyst. 4ou can also add a thixotropicadditive" which thickens the rubber and allows you to use it on a
vertical surface without it slumping.
'esmo$ite
This is an acrylic based powder and liquid mix offered as a
replacemant to fibre glass.
I have found it to be a bit too heavy for the puppets and a bit more
#crumbly# than resin and fibreglass when strength is needed. It#s
advantage over resin is that it does not have the fumes and is
therefore much more user friendly. I sometimes use it for the rigid
mould casing" where weight is not such an issue.
Polyester resi$ + *i(re %lass
Polyester resin is a plastic based liquid which when used with
fibreglass gives excellent strength for a reasonable weight. It is
ideal for picking up the detail in the silicone mould" and is what I
use choice to cast the head and hands of the puppet. It can be
coloured by mixing polyester pigments before adding the catalyst which
causes it to harden. The resin and its catalyst cause an exothermic
reaction" i.e. one which creates heat. ,hen laminating this is not
particularly noticeable" but if you are pouring solid resin casts then
the heat can be considerable. !owever this is unlikely if you are
making puppets as a solid resin cast is usually too heavy for anything
but the smallest of heads. The trick is to create the strongest and
most rigid structure with as little resin and fibreglass as possible.
